Rudy Giuliani has proclaimed that he made a mistake in joining (and not attending) the Iraq Study Group (hat tip Majikthise). He was perhaps unintentionally revealing:

Giuliani said the main reason he quit was that it “didn’t seem that I would really be able to keep the thing focused on a bipartisan, nonpolitical resolution.” [AP]

This tells us two things. First, that Giuliani considers “bipartisan, nopolitical” resolutions to be a good and necessary thing. Second, that he does not think he can provide such a resolution (at least when it comes to questions of war and national security).
